European shares rose on Thursday, boosted by gains in technology stocks, after strong forecasts from Micron and Qualcomm eased concerns about rising sector valuations, while a decline in oil prices provided additional support to the markets.

The pan-European STOXX 600 index rose 0.4% to 637.89 points, and Germany’s DAX index climbed about 0.3% to 24,824.74 points, while Britain’s FTSE and France’s CAC remained stable at 10,470.45 and 8,389.23 respectively.

The AI-related rally has resurfaced after US chipmakers Micron and Qualcomm unveiled strong forecasts, temporarily calming investor fears that the large gains made by global AI stocks may have exceeded their justifiable levels.
